A visual novel (ビジュアルノベル,bijuaru noberu) is an interactive game genre, which originated in Japan,[1][2] featuring text-based story with narrative style of literature and interactivity aided by static or sprite-based visuals, most often using anime-style art or occasionally live-action stills (and sometimes video footage).[3] As the name might suggest, they resemble mixed-media novels.

In Japanese terminology, a distinction is often made between visual novels (abbreviated NVL, derived from "novel"), which consist predominantly of narration and have very few interactive elements, and adventure games (abbreviated AVG, or ADV derived from "adventure"), a form of adventure game which may incorporate problem-solving and other types of gameplay. This distinction is normally lost outside Japan, where both NVLs and ADVs are commonly referred to as "visual novels" by international fans. Visual novels and ADVs are especially prevalent in Japan, where they made up nearly 70% of the PC game titles released in 2006.[4]

Visual novels are often produced for video game consoles, and the more popular games have occasionally been ported to such systems. The more famous visual novels are also often adapted into the light novel, manga or anime formats. The market for visual novels outside of East Asia is small, though a number of anime based on visual novels are popular among anime fans in the Western world.

Visual novels often feature highly detailed backgrounds and characters rendered in a style reminiscent of Japanese animation.

Visual novels are distinguished from other game types by their generally minimal gameplay. Typically the majority of player interaction is limited to clicking to keep the text, graphics and sound moving (many recent games offer "play" or "fast-forward" toggles that make this unnecessary), while making narrative choices along the way. Another main characteristic of visual novels are its strong emphasis on the prose, as the narration in visual novels are delivered through text. This characteristic makes playing visual novels similar to reading a book.[5]

Most visual novels have multiple storylines and more than one ending; the mechanic in these cases typically consists of intermittent multiple-choice decision points, where the player selects a direction in which to take the game. This style of gameplay is similar to story-driven interactive fiction, or the shorter and less detailed real-life gamebook books.[6] Many fans of visual novels hold them up as exceptions to the relatively weak storytelling in video games overall.

Some visual novels do not limit themselves into merely interactive fictions, but also incorporate other elements into them. An example of this approach is Symphonic Rain, where the player is required to play a musical instrument of some sort, and attain a good score in order to advance. Usually such an element is related as a plot device in the game.

Some shorter works do not contain any decision points at all. Most examples of this sort are fan-created. Fan-created novel games are reasonably popular; there are a number of free game engines and construction kits aimed at making them easy to construct, most notably NScripter, KiriKiri and Ren'Py.[7]

Many visual novels use voice actors to provide voices for the characters in the game. Often, the protagonist is left unvoiced, even when the rest of the characters are fully voiced. This choice is meant to aid the player in identifying with the protagonist and to avoid having to record large amounts of dialogue, as the main character typically has the most speaking lines due to the branching nature of visual novels.

Non-linear branching storylines are a common trend in visual novels, which frequently use multiple branching storylines to achieve multiple different endings, allowing non-linear freedom of choice along the way. Decision points within a visual novel often present players with the option of altering the course of events during the game, leading to many different possible outcomes.[8][9] An acclaimed example is Zero Escape: Virtue's Last Reward, where nearly every action and dialogue choice can lead to entirely new branching paths and endings. Each path only reveals certain aspects of the overall storyline and it is only after uncovering all the possible different paths and outcomes, through multiple playthroughs, that every component comes together to form a coherent well-written story.

The branching path stories found in visual novels represent an evolution of the Choose Your Own Adventure concept. The digital medium allows for significant improvements, such as being able to fully explore multiple aspects and perspectives of a story. Another improvement is having hidden decision points that are automatically determined based on the player's past decisions. In Fate/stay night, for example, the way the player character behaved towards non-player characters during the course of the game affects the way they react to the player character in later scenes, such as whether or not they choose to help in life-or-death situations. This would be far more difficult to track with physical books. More importantly, visual novels do not face the same length restrictions as a physical book. For example, the total word count of the English fan translation of Fate/stay night, taking all the branching paths into account, exceeds that of The Lord of the Rings. This significant increase in length allows visual novels to tell stories as long and complex as those often found in traditional novels, while still maintaining a branching path structure, and allowing them to focus on complex stories with mature themes and consistent plots in a way which Choose Your Own Adventure books were unable to do due to their physical limitations. Visual novels with non-branching plots, such as Higurashi When They Cry, Planetarian: The Reverie of a Little Planet, Muv-Luv Alternative, and Digital: A Love Story are rare exceptions within the genre.[6][7]

Many visual novels often revolve almost entirely around character interactions and dialogue choices, such as Ace Attorney and Tokimeki Memorial, usually featuring complex branching dialogues and often presenting the player's possible responses word-for-word as the player character would say them. Such titles revolving around relationship-building, including visual novels as well as dating simulations, such as Tokimeki Memorial, and some role-playing video games, such as Shin Megami Tensei: Persona, often give choices that have a different number of associated "mood points" that influence a player character's relationship and future conversations with a non-player character. These games often feature a day-night cycle with a time scheduling system that provides context and relevance to character interactions, allowing players to choose when and if to interact with certain characters, which in turn influences their responses during later conversations.[10]

As early as 1983, Portopia Serial Murder Case featured non-linear elements, which included traveling between different areas in a generally open world, a branching dialogue conversation system where the story develops through entering commands and receiving responses from other characters, and making choices that determine the dialogues and order of events as well as alternate outcomes, though there is only one true culprit while the others are red herrings. It also features a phone that could be used to dial any number to contact several non-player characters.[11] The game was well received in Japan for its well-told storyline and surprising twist ending, and for allowing multiple ways to achieve objectives.[12] Another more non-linear early example was Mirrors, released by Soft Studio Wing for the PC-8801 and FM Towns computers in 1990; it featured a branching narrative, multiple endings, and audio CD music.[13]

It is not uncommon for visual novels to have morality systems. A well-known example is the 2005 title School Days, an animated visual novel that Kotaku describes as going well beyond the usual "black and white choice systems" (referring to video games such as Mass Effect, Fallout 3 and BioShock) where you "pick a side and stick with it" while leaving "the expansive middle area between unexplored." School Days instead encourages players to explore the grey, neutral middle-ground in order to view the more interesting, "bad" endings.[14]

A common feature used in visual novels is having multiple protagonists giving different perspectives on the story. C's Ware's EVE Burst Error (1995) introduced a unique twist to the system by allowing the player to switch between both protagonists at any time during the game, instead of finishing one protagonist's scenario before playing the other. EVE Burst Error often requires the player to have both protagonists co-operate with each other at various points during the game, with choices in one scenario affecting the other.[15]Fate/stay night is another example that features multiple perspectives.[6]Chunsoft sound novels such as Machi (1998) and 428: Shibuya Scramble (2008) develop this concept further, by allowing the player to alternate between the perspectives of several or more different characters, making choices with one character that have consequences for other characters.[3][16]428 in particular features up to 85 different possible endings.[16]

Other notable examples of non-linear storytelling include ELF's most famous visual novel, YU-NO: A girl who chants love at the bound of this world (1996), which featured a science fiction plot revolving around time travel and parallel universes. The player travels between parallel worlds using a Reflector device, which employs a limited number of stones to mark a certain position as a returning location, so that if the player decides to retrace their steps, they can go to an alternate universe to the time they have used a Reflector stone. The game also implemented an original system called ADMS, or Automatic Diverge Mapping System, which displays a screen that the player can check at any time to see the direction in which they are heading along the branching plot lines.[17] Similar systems have later been employed in the 2010 role-playing games, Radiant Historia[18][19] and the PSP version of Tactics Ogre.[20]

There are role-playing video games that feature visual novel-style elements. A well-known example in the West is the Lost Odyssey, an RPG that features a series of visual novel-style flashback sequences called "A Thousand Years of Dreams".[3] These sequences were penned by an award-winning Japanese short story writer, Kiyoshi Shigematsu.[21] Another title is the Arc System Worksfighting game series Blazblue, which plays off of a complex fantasy setting where a one-hundred-year period is reset indefinitely with many variables. The many branching story lines in Story Mode can serve as stand-alone stories, but players must consider them together along with Arcade Mode stories to be able to fully understand the universe.

Another successful example is Sega's Sakura Wars series, which combined tactical role-playing game combat with visual novel elements, introducing a real-timebranching choice system where, during an event or conversation, the player must choose an action or dialogue choice within a time limit, or to not respond at all within that time. The player's choice, or lack thereof, affects the player character's relationship with other characters and in turn the characters' performance in battle, the direction of the storyline, and the ending. Later games in the series added several variations, including an action gauge that can be raised up or down depending on the situation, and a gauge that the player can manipulate using the analog stick depending on the situation.[22] The success of Sakura Wars led to a wave of games that combine role-playing and visual novel elements, including Thousand Arms, Riviera: The Promised Land, and Luminous Arc.[23]

Visual novels are commonly characterized with dialog boxes and sprites denoting the speaker. This is a recreation of the usual screen layout of a visual novel, generated by the Ren'Py game engine.

Although using the narrative style of Literature, visual novel has evolved a style somewhat different from print novels. In general, visual novels are more likely to be narrated in the first person than the third, and to present events from the point of view of only one character.

In the typical visual novel, the graphics comprise a set of generic backgrounds (normally just one for each location in the game), with character sprites (立ち絵,tachi-e) superimposed onto these; the perspective is usually first-person, with the protagonist remaining unseen. At certain key moments in the plot, special event CGcomputer graphics are displayed instead; these are more detailed images, drawn specially for that scene rather than being composed from predefined elements, which often use more cinematic camera angles and include the protagonist. These event CGs can usually be viewed at any time once they have been "unlocked" by finding them in-game; this provides a motivation to replay the game and try making different decisions, as it is normally impossible to view all special events on a single play-through.

Up until the 1990s, the majority of visual novels utilized pixel art. This was particularly common on the NEC PC-9801 format, which showcased what is considered to be some of the best pixel art in the history of video games, with a popular example being Policenauts in 1994.[12] There have also been visual novels that use live-action stills or video footage, such as several Sound Novel games by Chunsoft. The most successful example is Machi, one of the most celebrated games in Japan, where it was voted No. 5 in a 2006 Famitsu reader poll of top 100 games of all time. The game resembled a live-action television drama, but allowing players to explore multiple character perspectives and affect the outcomes. Another successful example is 428: Shibuya Scramble, which received a perfect score of 40 out of 40 from Famitsu magazine.[3]

Many visual novels also qualify as eroge, an abbreviation of 'erotic game'. These games feature sexually explicit imagery that is accessed by completing certain routes in the game, most often depicting the game's protagonist having sex with one of the game's other characters. Like other pornographic media in Japan, scenes depicting genitalia are censored in their original Japanese releases, only becoming uncensored if the game is licensed outside Japan. Certain eroge titles receive re-releases which exclude explicit content in order to be sold to a younger audience, such as ports to consoles or handheld systems where sexually explicit content is not allowed, and storylines referring to aforementioned sex scenes are often omitted from adaptations into other media, unless that media is also pornographic in nature, such as a hentai anime.

Traditionally, PC-based visual novels have contained risque scenes even if the overall focus is not erotic (similar to the "obligatory sex scene" in Hollywoodaction films). However, the vast majority of console ports do not contain adult material, and a number of recent PC games have also been targeted at the all-age market; for example, all of Key's titles come in family-friendly versions, although the content might still not be appropriate for children, and three have never contained adult content at all. Also, all of KID's titles are family-friendly.

Some of Japan's earliest adventure games were eroticbishōjo games developed by Koei.[24] In 1982, they released Night Life, the first commercial erotic computer game.[12] It was a graphic adventure,[25] with sexually explicit images.[12] That same year, they released another erotic title, Danchi Tsuma no Yūwaku (Seduction of the Condominium Wife), which was an early adventure game with colour graphics, owing to the eight-color palette of the NEC PC-8001 computer. It became a hit, helping Koei become a major software company.[24] Other now-famous companies such as Enix, Square and Nihon Falcom also produced similar erotic games in the early 1980s before they became famous for their role-playing video games. While some early erotic games meaningfully integrate the erotic content into a thoughtful and mature storyline, others often used it as a flimsy excuse for pornography.[12] The Japanese game Pai Touch! involves the protagonist gaining the ability to change the size of girls' breasts, and the adventures that ensue in trying to choose which girl to use the power on the most.

Another subgenre is called "nukige" (抜きゲー), in which sexual gratification of the player is the main focus of the game.[26]

In 1986, Square released the science fiction adventure game Suishō no Dragon for the NES console. The game featured several innovations, including the use of animation in many of the scenes rather than still images,[27] and an interface resembling that of a point-and-click interface for a console, like Portopia Serial Murder Case, but making use of visual icons rather than text-based ones to represent various actions. Like the NES version of Portopia Serial Murder Case, it featured a cursor that could be moved around the screen using the D-pad to examine the scenery, though the cursor in Suishō no Dragon was also used to click on the action icons.[27][28]

Hideo Kojima (of Metal Gear fame) was inspired by Portopia Serial Murder Case to enter the video game industry,[29] and later produced his own adventure games. After completing the stealth gameMetal Gear, his first graphic adventure was released by Konami the following year: Snatcher (1988), an ambitious cyberpunk detective novel, graphic adventure, that was highly regarded at the time for pushing the boundaries of video game storytelling, cinematic cut scenes, and mature content.[30] It also featured a post-apocalyptic science fiction setting, an amnesiac protagonist, and some light gun shooter segments. It was praised for its graphics, soundtrack, high quality writing comparable to a novel, voice acting comparable to a film or radio drama, and in-game computer database with optional documents that flesh out the game world. The Sega CD version of Snatcher was for a long time the only major visual novel game to be released in America, where it, despite low sales, gained a cult following.[31]

A popular subgenre of visual novels is the nakige (泣きゲー,"crying game"), which, as opposed to utsuge (鬱ゲー,"depressing game"), still usually has a happy ending. The main purpose of such a game is to make the player feel for the characters and to make them cry because of emotional scenarios which serve to have a bigger impact on the player after the game is over. These games often follow a similar formula: a comedic first half, with a heart-warming romantic middle, followed by a tragic separation, and finally (though not always) an emotional reunion. This formula was influenced primarily by Leaf's visual novel To Heart, released in 1997, and was further developed in the 1998 title One: Kagayaku Kisetsu e, developed by Tactics. After One was complete, the development team quit Tactics to form Key where they developed their first title Kanon, also based upon this formula. According to Satoshi Todome in his book, A History of Adult Games, Kanon was "heavily hyped [and] had gamers impatient until its release. It was only one game released by Key so far, and yet [it] had already sent major shockwaves around the industry. And yet another game [Air], two years later, sent even more shockwaves. Air was equally hyped and well received."[34]

In 2008, several of Key's visual novels were voted in the Dengeki poll of the ten most tear-inducing games of all time, including Clannad at No. 2, Kanon at No. 4, Air at No. 7, and Little Busters! at No. 10.[37] In 2011, several visual novels were also voted in Famitsu's poll of 20 most tear-inducing games of all time, with Clannad at No. 4, Steins;Gate at No. 6, Air at No. 7, Little Busters! at No. 10, and 428: Fūsa Sareta Shibuya de at No. 14.[38]

Dōjinshi (同人誌, often transliterated as doujinshi) is the Japanese term for self-published (fan-made) works. This includes (but is not limited to) dōjin games (同人ゲーム), also sometimes called dōjin soft (同人ソフト). These visual novel-style games are created as fan-made works based on pre-existing fandoms (usually anime and manga, but also for tv shows or even other pre-existing games and visual novels). Dōjinshi games are often based on romance (or shipping) between two characters, known as an otome game (乙女ゲーム) or dating sim; sometimes becoming sexual (or hentai), known as an eroge (エロゲ, a portmanteau of erotic game: (エロチックゲーム)).

Prior to the year 2000, few Japanese visual novels were translated into other languages. As with the visual novel genre in general, a majority of titles released for the PC have been eroge, with Hirameki's now-discontinued AnimePlay series a notable exception. As of 2014, JAST USA and MangaGamer are the two most prolific publishers of translated visual novels for the PC; both primarily release eroge, but have begun to diversify into the all-ages market in recent years, with titles such as Steins;Gate and Higurashi no Naku Koro ni respectively. In addition to official commercial translations, a vibrant fan translation scene exists, which has translated many free visual novels (such as Narcissu and True Remembrance) and a few commercial works (such as Umineko no Naku Koro ni and Policenauts) into English. Fan translations of Japanese visual novels into languages other than English such as Chinese, French, German and Russian are commonplace as well.

English translations of Japanese visual novels on video game consoles were rare until the release of the Nintendo DS, though some games with visual novel elements had been published in the Western world before then, such as Hideo Kojima's Snatcher. Following the success of mystery titles for the Nintendo DS such as Capcom's Ace Attorney series (which began on the Game Boy Advance in 2001), Cing's Hotel Dusk series (beginning in 2006),[40] and Level-5's Professor Layton series (beginning in 2007),[41] Japanese visual novels have been published in other countries more frequently. The success of these games has sparked a resurgence in the adventure game genre outside Japan.[40][42][43]
